If you want to use your Handibot on big 4x8 sheets of plywood, it is nice to have a flat sturdy workbench big enough to support them. I built one and describe how to build it on Instructables. See the details here, including a time-lapse of the build process: http://www.instructables.com/id/Very-STURDY-and-Flat-4x8-Workbench-Table/
